Welcome to the Global VLBI Alliance (GVA).

By its very nature, VLBI has always depended on international collaborations. These have led to the formation of several formal VLBI networks, which in turn regularly form combined arrays. The GVA facilitates the flow of information between VLBI networks, including sharing strategies, technical developments for compatibility, logistics, operations, and user support, and also promote, propose and coordinate common observational campaigns with these existing networks. In a multi-messenger scenario, the GVA will serve as contact point and framework of collaboration of the VLBI networks and other facilities. Additionally, it can encourage and support new VLBI activities. The GVA will also facilitate that adequate information is provided to the users by this unique common portal.
